Payload is designed with performance in mind, but its customizability
means that there are many ways to configure your app that can impact
performance.
While Payload provides several features and best practices to help you
optimize your app's specific performance needs, these are not currently
well surfaced and can be obscure.
Now:
- A high-level performance doc now exists at `/docs/performance`
- There's a new section on performance within the `/docs/queries` doc
- There's a new section on performance within the `/docs/hooks` doc
- There's a new section on performance within the
`/docs/custom-components` doc
This PR also:
- Restructures and elaborates on the `/docs/queries/pagination` docs
- Adds a new `/docs/database/indexing` doc

It is a common pattern to dynamically show and validate a select field's
options based on various criteria such as the current user or underlying
document.
Some examples of this might include:
- Restricting options based on a user's role, e.g. admin-only options
- Displaying different options based on the value of another field, e.g.
a city/state selector
While this is already possible to do with a custom `validate` function,
the user can still view and select the forbidden option...unless you
_also_ wired up a custom component.
Now, you can define `filterOptions` on select fields.
This behaves similarly to the existing `filterOptions` property on
relationship and upload fields, except the return value of this function
is simply an array of options, not a query constraint. The result of
this function will determine what is shown to the user and what is
validated on the server.
Here's an example:
```ts
{
name: 'select',
type: 'select',
options: [
{
label: 'One',
value: 'one',
},
{
label: 'Two',
value: 'two',
},
{
label: 'Three',
value: 'three',
},
],
filterOptions: ({ options, data }) =>
data.disallowOption1
? options.filter(
(option) => (typeof option === 'string' ? options : option.value) !== 'one',
)
: options,
}
```
Fixes https://github.com/payloadcms/payload/issues/10962
This fix addresses fields with timezones enabled specifically for not
time pickers. If all you want to do is pick a date such as 14th Feb, it
would store the incorrect version and display a date in the future for
people in the Pacific.
This is because Auckland is +12 offset, but +13 with Daylight Savings
Time. In our date picker we try to normalise date pickers with no time
to 12pm and so half the year we ended up pushing dates visually to the
next day for people in the pacific only. Other regions were not affected
by this because their offset would be less than 12.
This PR fixes this by ensuring that our dates are always normalised to
selected timezone's 12pm date to UTC.
There's also additional tests for these two fields from 3 main locations
to cover a wider range of possible timezones.
Adds support for timezone selection on date fields.
### Summary
New `admin.timezones` config:
```ts
{
// ...
admin: {
// ...
timezones: {
supportedTimezones: ({ defaultTimezones }) => [
...defaultTimezones,
{ label: '(GMT-6) Monterrey, Nuevo Leon', value: 'America/Monterrey' },
],
defaultTimezone: 'America/Monterrey',
},
}
}
```
New `timezone` property on date fields:
```ts
{
type: 'date',
name: 'date',
timezone: true,
}
```
### Configuration
All date fields now accept `timezone: true` to enable this feature,
which will inject a new field into the configuration using the date
field's name to construct the name for the timezone column. So
`publishingDate` will have `publishingDate_tz` as an accompanying
column. This new field is inserted during config sanitisation.
Dates continue to be stored in UTC, this will help maintain dates
without needing a migration and it makes it easier for data to be
manipulated as needed. Mongodb also has a restriction around storing
dates only as UTC.
All timezones are stored by their IANA names so it's compatible with
browser APIs. There is a newly generated type for `SupportedTimezones`
which is reused across fields.
We handle timezone calculations via a new package `@date-fns/tz` which
we will be using in the future for handling timezone aware scheduled
publishing/unpublishing and more.
### UI
Dark mode
Light mode
Continuation of #10741. Field-level admin options, including the
conditional logic and custom field components, are currently documented
within the "admin > customizing views" page. This makes them hard to
find because users, myself included, intuitively navigate to the fields
overview doc first to locate this information. Now, they are rendered
within "fields > overview" as expected. This should help keep the user
from jumping around from doc to doc and getting lost.
Although the "customizing fields" doc provides a big picture overview of
how to create custom field components, it is not explicit enough for
developers to know exactly where to start. For example, it can be
challenging to import the correct types when building these components,
and the natural place to go looking for this information is on the
fields docs themselves. Now, each field doc has its own dedicated
"custom components" section which provides concrete examples for fields
and field labels in both server and client component format, with more
examples to come over time such as using inputs directly, etc. In the
same vein, the "customizing fields" doc itself should probably be moved
to the fields overview section so it remains as intuitive as possible
when searching for this information.
### What?
This PR fixes numerous links across the docs, both internal docs links
and external links. This PR also fixes some minor formatting issues in
some places, as well as optically aligns the markdown tables in tables
that had broken links.
### Why?
To properly link readers to the correct location in the docs, and for
better formatting and easier consumption.
### How?
Changes to many `.mdx` files in the `docs` folder.
Notes:
- There are duplicative section id's in `docs/authentication/email.mdx`,
I've fixed one such link, but have left it as is for now.

## Description
Adds `virtual` property to the fields config. Providing `true`
completely disables the field in the DB, which is useful for [Virtual
Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges)
Disables abillity to query by a field with `virtual: true`.
Currently, they bloat the DB with unused tables / columns, which may as
well introduce additional joins.
